Stress annealing device for glass bottle production

Abstract

The invention relates to the technical field of glass production. The invention aims at providing a stress annealing device for glass bottle production. The device comprises a shell, and the shell comprises a heat preservation bottom plate, heat preservation side plates and a heat preservation top plate; vertical lifting hydraulic cylinders are arranged at the two ends of the heat preservation bottom plate, and the output ends of the lifting hydraulic cylinders face upwards and are connected with the heat preservation top plate; a plurality of annealing chambers are arranged on the heat preservation bottom plate in the shell; and a plurality of annealing mechanisms are arranged on the heat preservation top plate and correspond to the annealing chambers in number, each annealing mechanism comprises a vertical rotating main pipe, and the rotating main pipe is arranged on the heat preservation top plate in a penetrating mode and is in rotating fit with the heat preservation top plate through a bearing. Balanced annealing temperature control on the inside and the outside of the glass bottle can be realized, and the annealing quality can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a stress annealing device for glass bottle production. Background technique [0002] In the production process of glass bottles, annealing treatment is required after blowing to eliminate the internal stress of the glass bottle, prevent the glass from cooling too quickly, and from uneven cooling, which may cause the glass bottle to break. In short, the stress annealing treatment of glass bottles is to cool the glass bottles slowly and uniformly, or to cool them slowly and uniformly after a period of time. For traditional glass bottles, the general mesh belt conveying annealing furnace can meet the demand. [0003] However, for large glass bottles, due to the large volume and thick wall of the glass bottle, and limited by the closing structure of the bottle-shaped vessel, the internal heat is not easy to discharge, which leads to a large difference in the cooling rate be...
